Dutch Winterswijk Triassic fossils, new study

Originally posted on Dear Kitty. Some blog: This May 2018 video is called Dutch Minerals and [Triassic] Fossils / Winterswijk. I myself was at this quarry. Unfortunately, only the path at the top is accessible for the public. So, I saw only a willom warbler, not the nesting eagle owls and Triassic fossils below. From the University of Bonn in Germany: Fossil deposit is much richer than expected Paleontologist analyses finds from the Dutch town of Winterswijk January 14, 2019 It has long been known that a quarry near the Dutch town of Winterswijk is an Eldorado for fossil lovers. But even connoisseurs will be surprised just how outstanding the site actually is. A student at the University of Bonn, himself a Dutchman and passionate fossil collector, has now analyzed pieces from museums and private collections for his master’s thesis. He found an amazing amount of almost completely preserved skeletons, all between 242 and 247 million years old. The good condition is presumably due to particularly favorable development conditions. These make Winterswijk, which belongs to the so-called Germanic Basin, a cornucopia for paleontology. The study is published in the Paläontologische Zeitschrift. Jelle Heijne examined exactly 327 remains of marine reptiles for his master’s thesis — collected partly from public museums, but primarily from about 20 private collections. He was particularly impressed by the high quality of the finds: “Among them were more than 20 contiguous skeletons”, he emphasizes. “Only…

Singing humpback whales, new research

Originally posted on Dear Kitty. Some blog: This video from australia says about itself: Humpback Whale Singing Hervey Bay 2014 Be sure to have your volume up for this clip. The audio and video were filmed using a GoPro on separate days with the audio being some of the most stunning whale singing that we have heard in many years. The video is yet more footage of our curious friend ‘scratchy’. From the Wildlife Conservation Society: Giant singers from neighboring oceans share song parts over time January 8, 2019 Singing humpback whales from different ocean basins seem to be picking up musical ideas from afar, and incorporating these new phrases and themes into the latest song, according to a newly published study in Royal Society Open Science that’s helping scientists better understand how whales learn and change their musical compositions. The new research shows that two humpback whale populations in different ocean basins (the South Atlantic and Indian Oceans) in the Southern Hemisphere sing similar song types, but the amount of similarity differs across years. This suggests that males from these two populations come into contact at some point in the year to hear and learn songs from each other. The study titled “Culturally transmitted song exchange between humpback whales (Megaptera novaeangliae) in the southeast Atlantic and southwest Indian Ocean basins” appears in the latest edition of the Royal Society Open Science journal. The authors are: Melinda L. Rekdahl,…

Plant survivors of Permian-Triassic mass extinction

Originally posted on Dear Kitty. Some blog: This 26 February 2018 video from the USA says about itself: The Permian-Triassic Boundary – The Rocks of Utah The Great Dying! In this episode we head out to the Permian-Triassic boundary and try to discover what caused Earth’s Largest mass extinction event, 252 million years ago. After 4-months of research, I’m excited to finally release this exciting video! A pre-print of the scientific paper is available here. I’ve submitted this research to the journal “Global and Planetary Change” for peer review. By Laurel Hamers, 2:12pm, December 20, 2018: More plants survived the world’s greatest mass extinction than thought Fossils in a Jordanian desert reveal plant lineages that didn’t perish in the Great Dying Some ancient plants were survivors. A collection of roughly 255-million-year-old fossils suggests that three major plant groups existed earlier than previously thought, and made it through a mass extinction that wiped out more than 90 percent of Earth’s marine species and roughly 70 percent of land vertebrates. The fossils, described in the Dec. 21 Science, push back the earliest records of these plant groups by about 5 million years. “But it’s not just any 5 million years — it’s those 5 million years that span the Permian-Triassic boundary”, says study coauthor Benjamin Bomfleur, a paleobotanist at the University of Münster in Germany. The find adds to the growing list of land plants that survived the catastrophe known as…
